Roll dough on flour-dusted kitchen table until thin. Pull the dough further on top of the back of your hands until approximately 60cm × 60cm. (When you can read a newspaper through the dough, it's thin enough.)

Cut thick outer rim off dough and make sure bench surface is well dusted with flour.

Brush dough with liquid butter.

Spread sweet breadcrumbs over the lower quarter of the dough, leaving a 3cm rim to the bottom and the sides.

Place apple mix on top of breadcrumbs and fold rims of dough over apple mix.
